Patented Aug. 16, 1932 maven STATES FRANK B. VALLAIDOA, OF NEW BEDFORJ D, MASSACHUSETTS WINDOW SCREEN FIXTURE Application filed July 21, 1331; Serial No. 552,221. I, v

This invention relates to certain new and useful improvements in window screen fixtures. V

The primary object of the invention is to provide a fixture or attachment for window screens wherein a screen frame may be mounted in a window opening to be engaged with the side stiles thereof and capable of being slida-bly shifted without the aid of the usual 39 guide strips on the window stiles and cooperating grooves in the screen frame, as well as being movable in a hinge-like manner in the absence of hinge members.

A further object of the invention is to pro- 5 vide a screen fixture in the form of a resilient spring strip attached to opposite side edges of the frame of the screen which when the screen is in position in a window opening are compressed for retaining the screen in position.

Vith the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing Figure 1 is a fragmentary elevational view of a window frame with the improved screen and fixture in position therein;

Figure 2 is a fragmentary perspective view of the screen frame showing the spring retaining strip secured to one side edge thereof Figure 3 is a horizontal sectional View taken on line 38 of Figure 1, partly broken away, and showing the side edge springs under compression for retaining the screen frame in position and also the coil springs extending between the screen frame and window frame; and

Figure 4 is a horizontal sectional view, similar to Figure 3, showing the screen partially opened by pivotal movement at the coil spring retained side thereof.

Referring more in detail to the accompanying drawing, there is illustrated a window frame comprising side dials 5 and a sill 6 with a window screen set into the window opening and being of rectangular formation with upper and lower rails 7 and side rails 8. The screen ,frame has the usual screening 9 set within the frame rails' -7and8 and the fixtures for retaining the screen impositionin the opening of the window frame areas} sociated with the outer sides ofthe side rails 8. Each fixture includes a spring 'plate IO secured as by pins 11 or the like to the outer face 'of the rail 8 adjacent one longitudinal edge thereof, the spring. plate 10 beingfre versely bent uponitselfas at 12 to "provide an inwardly disposed strip 18 having the'free edge thereof normally engaged with the rail 8 as illustrated in Figures 2 and 4, the spring plate 10 'being reversely mountedon the opposite rails 8 of the screen frameas illustrated. The inner strip section- 13 of the spring plate l Ois normally spaced from the screen rail 8 so that when -the screen frame is in the position shown in Figure 3, the spring plates are compressed with the strip section 13 moved into flat engagement with the adjacent face of the rail 8 as shown in Figure 3, with the tension of the spring plate 7 acting to retain the screen frame in the win- 7 dow opening.

To prevent accidental displacement of the screen frame and also to permit the same to be moved in a hinge-like manner, coil springs 14 ar provided, preferably two in number as illustrated in Figure 1, having one end thereof attached as at 15 to the window frame while the other end is attached as at 16 to the adjacent screen rail 8. To facilitate movement of the screen, a handle 17 is carried thereby at the side opposite the spring attachment 14.

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent, it being noted that the spring plates 10 and their strip extensions. 13 operate to retain the screen frame in the window opening and when the coil springs 14 are disengaged from the screen frame, the latter may be slid in the window frame in the absence of the usual guide grooves and tongues. When the coil springs 14 are engaged with the spring frame, the latter may be moved in a hinge like manner as illustrated in Figure 4,

the coil springs 14 operating to return the screen frame to its closed operative position relative to the window frame and while they may have a tendency to retain the screen frame in position, the side spring plates associated with the screen frame rails 8 are intended to perform this function.

While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.

I claim 1. In a window screen fixture, the combination with a screen frame, of a spring strip secured to opposite side edges thereof, the spring strip including a reversely bent spring plate having one edge secured to the screen frame, with the reversely bent portion of the strip disposed adjacent the side rail of the screen frame.

2. In a Window screen fixture, the combination with a screen frame, of a spring strip secured to opposite side edges thereof,

and spring devices connecting one side edge of the screen frame to a window frame, the

spring strip including a reversely bent spring plate having one edge secured to the screen frame, with the reversely bent portion of the strip disposed adjacent the side rail of the screen frame. i

In testimony whereof I affix my signature.
